[Prior art]

 FIG. 3 is a schematic side view showing a correction tool which is an example of the conventional transfer tool described above, and FIG. 4 is an exploded perspective view of a supply core portion of the correction tool shown in FIG. Note that FIG. 3 shows a state in which the cartridge half on one side is removed. In these drawings, reference numeral 1 denotes a cartridge half on one side which constitutes a cartridge, and a cylindrical boss 2S that rotatably supports a gear 11, an annular rib 3S having the boss 2S as a center, and a boss. An annular gear train 4S located outside the rib 3S with the 2S as the center, a cylindrical boss 2T similar to the boss 2S that rotatably supports the winding core 31, and the boss 2T as the center. An annular rib 3T similar to the rib 3S and a plurality of guides 5 for guiding the transfer tape 51 fed from the supply core 21 are provided on the inner surface.

Reference numeral 11 denotes a gear whose lower surface abuts against the rib 3S. The first boss 12 has an annular shape in which the boss 2S is inserted, and is concentric with the first boss 12, and is located outside the first boss 12. An annular second boss 13 having four tongue pieces 13a provided with protrusions 13aa on the outer side of the upper side at equal intervals, and a tongue piece 14 having a protrusion on the lower side engaging with the gear train 4S are provided. It is included. Reference numeral 21 denotes a supply core, which is provided with a center hole 22 having an inner peripheral surface having a gear that meshes with the protrusion 13aa of the second boss 13 to be inserted. Therefore, by bending the tongue piece 13a inward, the supply core 21 and the gear 11 can relatively rotate.

Reference numeral 31 denotes a winding core whose lower surface abuts against the rib 3T, and which has a hole 32 into which the boss 2T is inserted and a gear portion 33 which is provided on the peripheral edge of the lower surface and meshes with the gear 11. . Reference numeral 41 denotes a head attached to the cartridge half 1, which projects the transfer tape 51 between the guides 5 to the outside of the cartridge half 1, and the wings 43 for guiding the transfer tape 51 to the projecting portion 42 face each other. It is provided.

Reference numeral 51 denotes a transfer tape, which has a white pressure-sensitive transfer layer as a transfer material carried on the outer surface of a synthetic resin base film. Reference numeral A denotes a transfer tool, which is composed of a cartridge half 1, a gear 11, a supply core 21, a winding core 31, a head 41 and a transfer tape 51. B indicates a transfer target, which is, for example, paper.

The radius of the gear 11 is larger than the radius of the gear portion 33, and the winding core 31 is rotated faster than the supply core 21 to apply tension to the transfer tape 51. The gear train 4S and the tongue piece 14 constitute a ratchet mechanism that rotates the supply core 21 only in the supply direction, and the tongue piece 13a and the center hole 22 constitute a slip mechanism. Further, the transfer tape 51 is wound around the supply core 21 with the pressure sensitive transfer layer side facing outward.

Next, the transfer of the pressure sensitive transfer layer to the transfer target B will be described. First, as shown in FIG. 3, the transfer tool A is moved in the direction of the arrow while pressing the entire width of the transfer tape 51 against the transfer target B by the protrusion 42 provided on the head 41, and the transfer tape A is fed out from the supply core 21. The transfer tape 51 is guided by the guide 5 and then projected to the outside of the cartridge by the head 41. The transfer tape 51 is guided again by the guide 5 and then wound on the winding core 31.

Therefore, by moving the cartridge toward the end portion of the correction portion while pressing the protruding portion 42 against the beginning portion of the correction portion of the transfer target B via the transfer tape 51, the pressure-sensitive transfer to the correction portion is performed. The layer can be transferred and the modification can be modified. When the pressure-sensitive transfer layer is transferred to the transfer target B, the transfer tape 51 is automatically paid out from the supply core 21 by the frictional force with the transfer target B.

Since the take-up core 31 meshes with the gear 11, the transfer tape 51 after transferring the pressure-sensitive transfer layer is automatically taken up by the take-up core 31 and repeated from the supply core 21. The slip mechanism adjusts the difference between the feeding speed of the transfer tape 51 fed from the supply core 21 and the winding speed at which the winding core 31 winds the transfer tape 51. .

[0010]

[Problems to be solved by the device]

 In the conventional correction tool, tension is applied to the transfer tape 51 by the slip mechanism, and the difference between the feeding speed of the transfer tape 51 and the winding speed of the transfer tape 51 is adjusted by the slip mechanism. When the transfer tape 51 is unwound from the core 21, a clicking sound is generated when the protrusion 13aa moves over the gear of the center hole 22 due to the operation of the slip mechanism, and it can be confirmed that the transfer tape 51 is operating normally. it can.

However, since the slip mechanism operates in steps, the transfer tape 51 cannot be smoothly fed out from the supply core 21. In addition, when the transfer tape 51 is unwound from the supply core 21, a clicking sound is generated, which may make it difficult for other people to know that the correction tool is being used.

The present invention has been made in order to eliminate the above-mentioned inconvenience, and the transfer tape can be smoothly fed from the supply core, and no noise is generated even when the slip mechanism operates. Is provided.

[0013]

[Means for Solving the Problems]

 In the transfer tool according to the present invention, the slip mechanism has one end portion locked to the boss of the gear that rotatably supports the supply core, and most of the remaining portion is pressed against the inner peripheral surface of the center hole of the supply core. It consists of a spiral torque spring.

[0014]

[Action]

 In the transfer tool according to the present invention, the slip mechanism is composed of a spiral torque spring. Therefore, when the torque spring slides on the inner peripheral surface of the center hole, the transfer tape feeding speed and the transfer tape winding speed are Adjust for differences.

[0015]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view of a supply core portion of a transfer tool according to an embodiment of the present invention, FIG. 2 is an explanatory view corresponding to a plan view showing an assembled state of the supply core portion, and FIGS. The same reference numerals are given to the same or corresponding portions as those in 4, and the description thereof will be omitted. The other parts have the same structure as the conventional example.

In FIG. 1, reference numeral 11A denotes a gear whose lower surface abuts on an annular rib 3S, into which a cylindrical boss 2S is inserted, and an annular boss 12A having an axial groove 12a on its outer peripheral surface is formed. It is provided. Reference numeral 21A indicates a supply core, which is provided with a central hole 22A into which the boss 12A is inserted. Reference numeral 61 denotes a spiral torque spring, which is made of SUS304 having a plate thickness of 0.2 mm and a plate width of 4 mm, for example, and is provided with a locking portion 62 formed by bending at one end. The diameter of the boss 2S is, for example, 4.4 mm, and the diameter of the central hole 22A is, for example, 7.2 mm, and a gap for inserting the torque spring 61 is secured between the two.

Next, attachment of the supply core 21A and the torque spring 61 to the gear 11A will be described. First, when the torque spring 61 is rolled and inserted into the center hole 22A of the supply core 21A, the torque spring 61 is pressed against the inner peripheral surface of the center hole 22A by its springback force. Then, when the boss 12A of the gear 11A is inserted into the center hole 22A and a part of the locking portion 61a is locked in the groove 12a of the boss 12A, the supply core 21A and the torque spring 61 are locked as shown in FIG. It can be attached to the gear 11A.

When the torque spring 61 is interposed between the boss 12A of the gear 11A and the supply core 21A in this way, the torque spring 61 slides on the inner peripheral surface of the center hole 22A, so that the transfer tape 51 moves. The difference between the feeding speed and the winding speed of the transfer tape 51 can be adjusted. Therefore, since the torque spring 61 smoothly slides on the inner peripheral surface of the center hole 22A, the transfer tape 51 can be smoothly fed out from the supply core 21A. Moreover, no sound is generated even when the slip mechanism operates, so that it is not possible to know that the transfer tool is used by the people around.

Although the torque spring 61 is made of SUS304 in the above-described embodiment, it is needless to say that the torque spring 61 may be made of other material, such as synthetic resin, as long as it can function similarly. . Although the transfer tape 51 carrying the transfer material as the pressure-sensitive transfer layer has been described as an example, the transfer material may be another transfer tape having, for example, an adhesive layer, an adhesive layer, or a heat-sensitive transfer layer. It goes without saying that it is good.

[0020]

[Effect of device]

 As described above, according to the present invention, the slip mechanism has one end portion locked to the boss of the gear that rotatably supports the supply core, and most of the remaining portion is the inner peripheral surface of the center hole of the supply core. Since it is composed of a spiral torque spring that is pressed into contact with the roller, the difference between the transfer tape feeding speed and the transfer tape winding speed can be adjusted by sliding the torque spring on the inner peripheral surface of the center hole. . Therefore, the torque spring slides smoothly on the inner peripheral surface of the center hole, so that the transfer tape can be smoothly fed out from the supply core. Moreover, no sound is generated even when the slip mechanism operates, so that it is not possible to know that the transfer tool is used by the people around.
